Dough Characteristics of Korean Wheat Flour

국산 밀가루의 반죽특성

In order to increase the Korean wheat-cultivators' incomes as well as to promote their consumptions, the native wheat of 11 varities (Chokwangmil, Geurumil, Eunpamil, Tapdongmil, Woorimil, Olgeurumil, Alchanmil , Gobunmil, Geungangmil Seodunmil and Suwon 265) were investigated on dough properties to compared with those of two imported wheat varieties, DNS (Dark Northern Spring Wheat) and ASW (Austrlian Standard White). In dough stickiness, Chokwangmil was highest as 81.78, and the mean value of native wheat was 53.98 g. ASW and DNS showed the stickiness values of 58.7 g and 52.9 g, respectively. Tapdongmil was highest in the tensile tone of dough as 87.6 g. In the texture test, the highest elasticity, gumminess, firmness and chewiness were observed in Woorimil as values of 0.980, 1,022.8, 1,562.7 and 1,001.9, respectively, while the highest cohesiveness and adhesiveness were obtained from Suwon 265 and Geurumil, respectively, as 0.710 and -609.4. In amylogram properties, the initial gelatinization temperature was ranged from 65$^{\circ}C$ to 69$^{\circ}C$, and maximum, minimum and final viscosities were highest in Woorimil as 1,140, 1,100 and 1,730 BU, respectively. In farinogram, water absorption rate was highest in Suwon 265 as 65.1%, which required the longest dough arrival time of 3.5 min. Dough developing time, weakening and stability were longest in Gobunmil as 9.7. 32.1 and 29.9 min., respectively. The resistance of dough was highest in Olgeurumil as 110 BU.

우리밀 생산농가의 소득증대와 소비촉진을 위한 연구로써 국내 육성 11개 밀품종인 조광밀, 그루밀, 은파밀, 탑동밀, 우리밀, 올그루밀, 알찬밀, 고분밀, 금강밀, 서둔밀, 수원 265호와 수입밀인 DNS Dark Northern Spring Wheat) 및 ASW (Australian Standard White) 등에 대하여 반죽특성을 살펴보았다. 밀가루 반죽의 점착성은 조광밀이 81.8g으로 가장 컸으며, 국산밀의 평균이 54.0 g, 수입밀 DNS 52.9 g, ASW 58.7 g 이었다. 인장력은 탑동밀이 87.6 g으로 가장 컸다. 조직감중 탄성, 껌성, 견고성 및 씹힘성은 우리밀이 각각 0.980, 1.022.8, 1,562.7. 1,00.9로 가장 높았으며, 응집성은 수원 265호가 0.710, 부착성은 그루밀이 -609.4로 가장 높았다. Amylogram특성에서 밀가루의 호화개시온도는 65-69$^{\circ}C$ 범위이었으며, 최고점도와 최저점도 및 5$0^{\circ}C$ 냉각시 최종점도에서 우리밀이 각각 1,140 B.U., 1,100 B.U., 1,730 B.U.로 가장 높았다. Farinogram 특성에서 흡수율은 도달시간이 3.52분으로 가장 긴 수원 265호가 65.1%로 가장 컸으며, 반죽의 형성시간과 약화도 및 안정도에서 고분밀이 각각 9.7분, 32.1분 및 29.9분으로 가장 길었으며, 반죽의 저항성은 올그루밀이 110 B.U.로 가장 높았다.
